3. Rule of thumb is if either foot of the batter is somewhere abeam the plate then his other foot won't be out when he hits. So what if that's not the case? Between innings surreptitiously pace off three footsteps from the middle of the plate and leave a toe print. When the offending batter is at the plate watch where his foot lands on the swing and miss. Oh wait, he didn't swing. Was that because it was a ball or he was taking a pitch? Since you didn't track it call it a ball. Next pitch, he swung and missed and you definitely saw his heel just clear your toe mark. Nothing of course since no contact. Next pitch, a stride and checked swing, but his foot was closer to your faded toe print, but no matter, appeal the checked swing to your partner, who gives you a strike as you hear some chatter about "it was down the middle, why are you checking". Next pitch, you decide tracking the pitch is more important than where the batters foot lands. Batter hits it and you don't have a clue where his foot landed.
There are some cases where the stars align and you get this but there is a reason why it is reviewable in MLB.
